It is an object of the invention to provide a lock of improved` construction in which a forcible retraction of the bolt or bolts from within the lock keeper will be prevented.

It is a further object to provide a` device of this lcharacter in which the bolt ,or bolt-s will be readily Aprojeetable within a keeper or retractable therefrom vwhen properly opf erated.

tion of each of which will be individually simple and which may be readily assembled by comparatively unskilled labor to provide an improved lock operating over long Vperiods of time withfreedom from mechanical difficulty.l j A A For. a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings in which: l

Figure 1 is a partly sectional side elevation of a lock embodying the improved construction of the present invention andshowing j. y y j f. viding the rotatable bolts is normally prethe parts thereof in retracted position; v Fig. 2 is asimilar view, showing the parts partially projected; y y Fig. 3 isA a view corresponding to Figs. 1 and 2, with the rear portion of the casing projected; n j

Fig. 4 is. a fragmentary face view of the interior of the lock case; j

Fig. 5 is an enlarged sectional viewataken along the lines 5 5 of Fig. 1; and

Fig. 6 is a transversesectional view taken along the lines 6 -6 o-f Fig. 1.

In these several views the numeral 10 indicates-a case which may be formed of any suitable material, and within which a dead-bolt 11 is slidably mounted this bolt being formed with bores 12 (in the present exemplification two in number1 extending in its direc-tion of travel, and eac of these bores mounting rotatable bolts 13 having oblong heads 14.

' In order to effect a projection an d retraction of this `bolt assembly a carrier is secured to and vextends from the rear edge of the dead-bolt 11, this carrier in the present instance including a T-shaped plate 15 riding upon guidesV 15 having the outer ends of its arms flanged inwardly as at 16. As lhas been best 'shown inFigS. 2, 3 and 5,

broken away, and showing the parts Wholly Another object is that of yproviding a lock embodying anumber of parts, the construc-k the plate 15 is formed with akey-hole slot'17, j

.'I`hus, when the crank is oscillated the pin 18, which is connected with the plate in a manner hereinafter described, will cause this plate. and the bolt assembly to be moved out `wardly or retractedwithin the lock case.

The rear ends ofV the shafts 13 providing the rotatablebolts are each transversely bored and receive a pin22, the length of'which is in excess of the ldiameter of the shaft with which itis associated. The rear end of the dead-bolt 11 is Vformed with. grooves or,as

shown, slots 23, disposedat a tangent to the direction of travel ofthe bolt assembly, and

the ends of the pins 22 ride withinthese slots. The lock case 10 carries railsl ,24, vwhich lie .at a point adjacent the 'path of travel of the bolt-s 13, and the pins 22 are yofsuch a length that their innerends lie adjacent the contact edges of the rails 24 when the boltassembly is retracted these edges being preferably beveled., Thus, a rotationof the shafts provented, fand, as a consequence, whenthe bolt 25 conveniently forma part of the lock case and aredi'sposed in positions spaced from the outer edges 26 of the rail members 24 and in line with the path of travel of the pins. As a consequence, it will be` understood that, upon the bolt assembly being projected to a point at which the pins 22 engage the abutments 25, their further movement as a 'unit wit-h the dead-bolt will'be prevented and they will re* main in their projected position during'the continued ,forward movement of the latter. Incident to thetangentially-eXtending slots n 23, the side edges of which engage the pins 22, this movement of the dead-bolt with respect tothe shafts 13 will resultin a rotation of the latter, so that the' heads 14 carried by the shafts willi beprocked.

Again'eonsid'ering the sequence of operations with the parts in the position shown in Fig. 1, the heads 14 in the present embodiment of the invention will be disposed longitudinally of the end edge of the lock case and recessed therein. A thrust upon'the extension-plate 15 will result in the bolt assembly moving forward as one unit to the position shown in Fig. 2, the shafts 13 remaining (not shown) which has an inwardly-extend-k A continued thrust.

ing flange or flanges. upon the dead-bolt will cause the latter to move outwardly to a positionV beyond the forward edge of the lock case, and the 'shafts 13 .to revolve to the position shown` in Fig. '3, at which position a further outward inovement of the parts is prevented; it being noted that'the ends of the pins 22 will ride into the spaces extant between the edges 26`ofthe track-members and the edges of the abutnients 25. In such position a swinging movement of the dead-bolt is prevented, incident to its engagement with the keeper. A retraction of the rotatable bolts'is precluded, in that the heads thereof will engage with the keeper flange' Aif forcible retraction is attempted. If, now, the movement of the parts is reversed, i. e., a pull is exerted upon the lvdead-bolt, it will be apparent that the shafts 13 cannot move longitudinally of the llock ycase for vvthe reason that the pins, in engagement with the edges 26 of the track-members, will prevent this occurrence. However, the dead-bolt will move rearwardly to the position shown in Fig. 2, and the pins 22 in cooperation with the edges of the slots 23, will Vcause the shafts 13 tol rotate axially to the position also shown in this figure; in 'which the inne-r pin ends clear the edge-:3 of the track-membersand the bolt heads will clear the keeper flanges i'f'retiacted. There upon, the bolt assembly maybe wholly ree tracted from within thelock case to the positionshown in Fig. 1.

With al view properly to'connect the plate 15 with the crank-member, it will be observed in thev embodiment illustrated-reference Vbeing had 'particularly to Fig. 't6-that the pin v18 has a head 27 yat its outer end, `the pinportion; ridinv between the arms ofthe crank 19, andthe liead engaging the inner faces of these arms to prevent accidental detach-` ment. `The pin is continued in the form of a boss or stud 28 having'at its outer end a lU-shaped recess 29 which f is intended for engagement withthe extension of a crank operated by a key (not shown). The stud 28 has a transverse bore, within which a tube 30 is mounted, these elements frictionally vcontacting normally to prevent relative movement thereof. The lower endof the tube Y is inturned'as at 31, and the upper end thereof is outturned as at 32,v the latter providing a iiange'whichengages lthe upper face 'of Jrhe stud to limit the projection of the tube. A

rod 'extends within the tube and beyond "the ends of .the same and has 'reduced end- 'portion's'B/f, which 'extend 'within notches 35 formed in the'flanges 16 of the .plate V15. A

spring 36 is coiled about the rod 33 and has one of its ends pressing against the inner Yface of the upper flange 16, its opposite end presse ing Vagainst the inner face of the inturned yflange 31 of the tube. As :a consequence, the stud 28 lis normally pressed downwardly,

from such position,` and, on the other hand,

Ait cannot move beyond such position, in that the stop pin 37 mounted by the case' will prevent this. Obviously, as the' crank is swung the spring 36 will be compressed, and upon A reaching a position beyondjdea'd: center, the

`spring will fully project the bolt assembly.

"Be Y Thisconnecting and actuating'device is preferably applied to vthe' plate 15 prior tothe introduction of the latter inthe crank l case. Such application isy accomplished simply by taking the'devifce as a unit, in serting the head 27 through the enlarged portion of the keyhole slot V,17 ,and thenjfoicing the stud 28 upwardly until the parts ast sume the position shown in Fig. 5', in which position the hea-d cannot register' with Athe enlarged portion of the slot, and, conse'- quently,-witli the reduced end-portions 811 of the rod 33 within the notchesb the device cannot become accidentally removed from tliepglate. The dead-bolt and plate are now placed within the lock case, care being' taken that the pin 18 be disposed betweentliefarms bolts are introduced intotlfreV bores of the 4of the crank 191. Thereafter, 4the rotatable dead-bolt 11, and the pins 22 are droppedinto place. Obviously, upon the cover plate (not shown) being applied, the parts cannot of themselves become disassembled, and it-willA be understood that the foregoingv operations maybe accomplished with minimum effort, time and skilled labor. Y

"Flins, among others, the objects oftliisin` vention have been accomplished, and `since certain changes maybe made in the above construction, and differentl embodiments ofthe Vies invention could be 'madewithout departing Y l from the scope tliereof,'it is 'intended that all mat-ter contained in the abovedescription or shown in the accompanyingdrawings shall be interpreted as illustrative and not in-a'limiting sense. f j y f f It is also to beunderstoodvthat the following claims are intended to V,cover all ofthe neric and specific features V.ofthe invention herein described and all'statementsof the scope of the invention which as a matter 'of language might'be said to fall therebetween.
